Purpose – The purpose of the study is to explore how productivity can be improved in an assembly line in manufacturing industry. In order to fulfill the purpose, following three research questions have been formulated: 1. How can an assembly line be designed? 2. Which potential improvement areas can be found in an assembly line? 3. How can assembly line balancing be used to improve productivity? Method – A case study was performed in order to answer the research questions. A combination of quantitative and qualitative data have been collected. To build an understanding of existing theories and research within the study area, a literature study was conducted which formed a theoretical framework. Parallel to the literature study, empirical data was collected through a case study. Data collection methods included observations, document studies, time measurements and focus group meetings. The reviewed theories and the collected data were later analyzed and a result was generated. Findings – In order to improve productivity, Theory of Constraints enabled the identification of potential improvement areas. To address the improvement areas, Assembly Line Balancing was found an appropriate method. Through the case study it was found that through Assembly Line Balancing, a reduction of takt time can be achieved which opens up the possibility to increase the production volume. Also, when re-allocating operators between work tasks, a reduction in numbers of operators is possible which results in lower costs. By lowering costs and increasing production volume, improved productivity is achieved. Implications – This study presents an application of the two improvement methods Theory of Constraints and Assembly Line Balancing in a manufacturing industry. Therefore, the thesis can be used as a basis when performing improvement work related to reduction of takt time in other manufacturing industries, to gain a better understanding for the implementation of the studied methods. Limitations – One limitation of the study was the pandemic Covid-19, which enforced restrictions on the case company. This disturbed the conduction of the case study since less focus group meetings were conducted, and suggested improvements could not be tested. Another limitation was the limited study time frame. Consequently, the collected time measurements were relatively few and the study scope was delimited to only packaging activities. To increase reliability, a more extensive time frame is necessary. The analysis has been adopted to the situation at the case company. The conclusions may hence be biased, which could restrict to what extent the study can be generalized.

Aircraft design is a major challenge in the age of electro-mobility, which is mainly due to the high demands on weight restrictions. Battery electric airplanes either are designed as gliders or have limited range. The current developments in the area of batteries and of hydrogen fuel cells give a huge potential for future activities extending the operational area of CS-23 airplanes with electric propulsion. The study presented describes the dimensioning of a fuel cell drive train system for CS-23 airplanes including potentials and design optimizations. Different hydrogen fuel cell electrification concepts are analysed and compared, what is followed by an analysis of the system components. Further, different hydrogen storage systems for mobile applications and their operational handling abilities are studied. The system requirements for the CS-23 Airplane are defined, including the optimal configuration for the investigated airplane, including the battery capacity for the take-off phase. The concept closes with a discussion on system requirements by defining command variables and a discussion on trade-off decisions. / Die Konstruktion von Flugzeugen stellt mit dem Wandel zur Elektromobilität eine große Herausforderung dar, was vor allem auf die hohen Anforderungen an die Gewichtsbeschränkung zurückzuführen ist. Batterieelektrische Flugzeuge sind entweder als Segelflugzeuge konzipiert oder haben eine begrenzte Reichweite. Die aktuellen Entwicklungen auf dem Gebiet der Batterien und der Wasserstoff-Brennstoffzellen bieten ein großes Potential für ein zukünftig erweitertes Einsatzgebietes von CS-23 Flugzeugen mit Elektroantrieb. Die vorgestellte Studie beschreibt die Dimensionierung eines Brennstoffzellen-Antriebsstrangs für CS-23-Flugzeuge einschließlich Potentialen und Design-Optimierungen. Es werden verschiedene Wasserstoff-Brennstoffzellen-Elektrifizierungskonzepte analysiert und verglichen, worauf eine Analyse der Systemkomponenten folgt. Weiterhin werden verschiedene Wasserstoffspeichersysteme für mobile Anwendungen und deren betriebliche Handhabbarkeit untersucht. Die Systemanforderungen für das CS-23 Flugzeug werden definiert, einschließlich der optimalen Konfiguration für das untersuchte Flugzeug, einschließlich der Batteriekapazität für die Startphase. Das Konzept schließt mit einer Diskussion über die Systemanforderungen.

Purpose: The purpose of this study is to explore the environmental impact of e-commerce, considering the effects on CO2e emissions from transportation and implications on product packaging.  Method: The research approach used in the study is an exploratory single case study design. The research questions were answered by using both qualitative and quantitative methods and the data collection methods used were interviews and document analyses in combination with a literature review.  Findings: The study shows that there is no straightforward answer to whether e-commerce is a better option environmentally speaking or not since it very much depends on the context and circumstances. Regarding transportation, e-commerce and especially home delivery, emitted least CO2e emissions. It was also shown that electric cars were the most environmentally friendly option considering consumer trips. Regarding packaging, it was shown that e-commerce resulted in larger packages and thus more CO2e emissions and waste.  Originality: The study contributes to an understanding of the environmental implications of e-commerce, and therefore, it can support companies in their progress toward becoming a more sustainable business. Limitations/delimitations: The study is limited to one case company and focuses on domestic deliveries within Sweden. Returns of products will not be included in any calculations. Emissions resulting from producing more packaging material, or the transportation of packaging material before usage, are not considered.  Theoretical implications: The study contributes to existing research within the area since it covers a different context by studying a manufacturer and adds a new perspective by considering different fuels for consumer trips in the calculations.  Managerial implications: Based on the result of the study practical suggestions for companies to reduce their environmental impact are presented, for example, implement a standard packaging procedure and outsource logistics activities to 3PL companies. / Syfte: Syftet med denna studie är att undersöka miljöeffekterna av e-handel, med beaktande av effekterna på CO2e utsläpp från transport och konsekvenser för produktförpackningar. Metod: Forskningsmetoden som används i studien är en undersökande design för enstaka fallstudier. Forskningsfrågorna kan besvaras med både kvalitativa och kvantitativa metoder och de datainsamlingsmetoder som använts är intervjuer och dokumentanalyser i kombination med en litteraturöversikt. Resultat: Studien visar att det inte finns något enkelt svar på om e-handel är ett bättre alternativ miljömässigt eller inte, eftersom det beror mycket på sammanhang och omständigheter. När det gäller transport, e-handel och särskilt hemleverans, släppte de ut minst CO2e utsläpp. Det visades också att elbilar var det mest miljövänliga alternativet med tanke på konsumentresor. När det gäller förpackningar visades det att e-handel resulterade i större paket och därmed mer CO2e utsläpp och avfall. Originalitet: Studien bidrar till en ökad förståelse för miljöpåverkan av e-handel, och kan därför stödja företag i deras framsteg mot att bli en mer hållbar verksamhet. Begränsningar: Studien är begränsad till ett fallföretag och fokuserar på inrikes leveranser inom Sverige. Retur av produkter ingår inte i några av beräkningarna. Utsläpp från produktion av mer förpackningsmaterial eller transport av förpackningsmaterial före användning beaktas inte. Teoretiska implikationer: Studien bidrar till befintlig forskning inom området eftersom den täcker ett annat sammanhang genom att studera en tillverkare och lägger till ett nytt perspektiv genom att beakta olika bränslen för konsumentresor i beräkningarna. Praktiska implikationer: Baserat på resultatet av studien presenteras praktiska förslag för företag för att minska sin miljöpåverkan, till exempel genom att implementera en standardiserad process för att paketering och lägga ut logistikaktiviteter till 3PL-företag.

Svensk e-handel noterade år 2020 den högsta tillväxten sedan mätningarnas start. Digitaliseringens utbredande bland den stora befolkningen ses som den stora orsaken till e-handels exponentiella tillväxt, vilket prognostiseras fortsätta växa nästkommande år. E-handelns tillväxtpotential skapar både möjligheter och utmaningar. Många av möjligheterna handlar om trotsade distansbarriärer. Utmaningarna hittas bland annat i att möta kundernas krav på korta ledtider, vilket är ett av områdena som förpackningar kan underlätta. Dessutom utgör förpackningar inom e-handel kundbemötandet eftersom de är det första och enda fysiska bemötandet företaget får med konsumenten.  Studien har utförts på ett sportrelaterat fallföretag inom detaljhandeln. Fallföretagets e-handel har likt övriga branschen ökat enormt senaste åren vilket fångat deras intresse om hur deras förpackningar kan anpassas bäst till e-handeln. Fallföretaget har identifierat fyra faktorer vilka de anser påverkar förpackningens prestanda; funktionalitet, miljö, kundupplevelse och kostnad.  Syftet med studien är att undersöka hur förpackningar kan anpassas till e-handel utifrån faktorerna funktionalitet, miljö, kundupplevelse och kostnad. Detta ska ligga till grund för att ge förbättringsförslag till fallföretagets fortsatta arbete med e-handelsförpackningar. För att besvara syftet har intervjuer och litteraturstudier genomförts. Genom litteraturstudierna har teori om e-handel och förpackningslogistik identifierats och via intervjuerna har nuläget presenterats och brister samt förbättringsområden insamlats. Litteraturen påvisar viktiga funktionskategorier för e-handelsförpackningar vilka är logistikfunktioner, marknadsfunktioner och miljöfunktioner. De brister som framkom från fallföretaget var kommunikations-, materialåtgångs- och kostnadsmätningsbrister.  Studien mynnar ut i sju aspekter som anses viktiga vid anpassning av förpackningar inom e-handel vilka är att; maximera fyllnadsgraden, att skydda varan och vara slittålig, stödja retursystemet, utnyttja kommunikationsfunktionen, minska materialåtgången, öka hanterbarheten och utforma förpackningen för återanvändning. Utifrån dessa faktorer kan fallföretaget fortsätta utveckla sina e-handelsförpackningar.  Det teoretiska bidraget av studien är en utvecklad kostnadsmodell där en ny parameter har identifierats. Studiens praktiska bidrag till fallföretaget är att utveckla kommunikationsfunktionen, analysera förpackningskostnaden holistiskt samt att använda en förpackningsprocess som bättre kan anpassa förpackningarna till produkterna.

Flexible electronics has attracted significant attention in the recent past due to the booming wearables market in addition to the ever-increasing interest for faster, thinner and foldable mobile phones. Ultra-thin bare silicon ICs fabricated by thinning down standard ICs to thickness below 50 μm are flexible and therefore they can be integrated on or in polymer foils to create flexible hybrid electronic (FHE) components that could be used to replace rigid standard surface mount device (SMD) components. The fabricated FHE components referred as chip foil packages (CFPs) in this work are ideal candidates for FHE system integration owing to their ability to deliver high performance at low power consumption while being mechanically flexible. However, very limited information is available in the literature regarding the reliability of CFPs under static and dynamic bending. The lack of such vital information is a major obstacle impeding their commercialization. With the aim of addressing this issue, this thesis investigates the static and dynamic bending reliability of CFPs. In this scope, the static bending reliability of CFPs has been investigated in this thesis using flexural bending tests by measuring their fracture strength. Then, Finite Element Method (FEM) simulations have been implemented to calculate the fracture stress of ultra-thin flexible silicon chips where analytical formulas may not be applied. After calculating the fracture stress from FEM simulations, the enhancement in robustness of ultra-thin chips (UTCs) against external load has also been proved and quantified with further experimental investigations. Besides, FEM simulations have also been used to analyse the effect of Young’s Modulus of embedding materials on the robustness of the embedded UTCs. Furthermore, embedding the UTCs in polymer layers has also been experimentally proven to be an effective solution to reduce the influence of thinning and dicing induced damages on the robustness of the embedded UTCs. Traditional interconnection techniques such as wire bonding may not be implemented to interconnect ultra-thin silicon ICs owing to the high mechanical forces involved in the processes that would crack the chips. Therefore, two novel interconnection methods namely (i) flip-chip bonding with Anisotropic Conductive Adhesive (ACA) and (ii) face-up direct metal interconnection have been implemented in this thesis to interconnect ultra-thin silicon ICs to the corresponding interposer patterns on foil substrates. The CFP samples thus fabricated were then used for the dynamic bending reliability investigations. A custom-built test equipment was developed to facilitate the dynamic bending reliability investigations of CFPs. Experimental investigations revealed that the failure of CFPs under dynamic bending was caused mainly by the cracking of the redistribution layer (RDL) interconnecting the chip and the foil. Furthermore, it has also been shown that the CFPs are more vulnerable to repeated compressive bending than to repeated tensile bending. Then, the influence of dimensional factors such as the thickness of the chip as well as the RDL on the dynamic bending reliability of CFPs have also been studied. Upon identifying the plausible cause behind the cracking of the RDL leading to the failure of the CFPs, two methods to improve the dynamic bending reliability of the RDL have been suggested and demonstrated with experimental investigations. The experimental investigations presented in this thesis adds some essential information to the state-of-the-art concerning the static and the dynamic bending reliability of UTCs integrated in polymer foils that are not yet available in the literature and aids to establish in-depth knowledge of mechanical reliability of the components required for manufacturing future FHE systems. The strategies devised to enhance the robustness of UTCs and CFPs could serve as guidelines for fabricating reliable FHE components and systems.

El presente trabajo a realizar se basa en la viabilidad, escalabilidad y pertinencia del método científico respecto al producto “nuggets a base de cushuro, lentejas y quinua” con la finalidad de llevarlo al mercado para satisfacer las necesidades del público objetivo y suprimir el problema encontrado. Una alimentación balanceada a lo largo de la vida ayuda a prevenir enfermedades y es aquella que contribuye con alimentos nutricionales de cada individuo. Asimismo, nos enfocamos en aportar con la oferta y comercialización de productos saludables dentro de Lima Metropolitano, debido a que existe una escasa oferta de productos sanos en el país por el elevado costo de fabricación y porque la mayoría son importados. Se quiere dar a conocer el producto como innovador y sobre todo resaltar su valor agregado mediante las propiedades nutricionales que contienen estos súper alimentos encontrados solo en esta región del Perú. En la actualidad existen empresas que comercializan este tipo de productos, los que tienen mayor impacto en el mercado en su mayoría son los competidores indirectos que elaboran nuggets convencionales a base de pollo. No obstante, hay una industria reducida que fabrica alimentos saludables y las comercializa, enfocados en un segmento pequeño de la población, la cual paga más por productos diferenciados y sanos. Así que, nuestra propuesta es satisfacer a ese segmento de personas que, apuesta por un producto nutritivo, accesible al precio y agradable al consumirlo. / The present work to be carried out is based on the viability, scalability and relevance of the scientific method with respect to the product "nuggets based on cushuro, lentils and quinoa" in order to bring it to the market to satisfy the needs of the target audience and eliminate the problem encountered . A balanced diet throughout life helps prevent diseases and is one that contributes with nutritional food for each individual. Likewise, we focus on contributing with the supply and marketing of healthy products within Metropolitan Lima, due to the fact that there is a scarce offer of healthy products in the country due to the high cost of manufacturing and because most are imported. It wants to publicize the product as innovative and above all highlight its added value through the nutritional properties of these super foods found only in this region of Peru. There are currently companies that market this type of product, the ones that have the greatest impact on the market, the majority are indirect competitors that make conventional chicken-based nuggets. However, there is a small industry that manufactures and markets healthy foods, focused on a small segment of the population, which pays more for differentiated and healthy products. So, our proposal is to satisfy that segment of people who are committed to a nutritious product, accessible at a price and pleasant to consume. / Trabajo de investigación

<p>Funkcionalni materijali na osnovu elektrospinovanih nanovlakana nalaze sve veću primenu u raznim oblastima industrije: biomedicina, farmacija, senzori, filrtacija, ambalaža itd. Elektrospining tehnika je jedna od metoda za dobijanje materijala na osnovu nanovlakana iz polimernih rastvora kori&scaron;ćenjem visokog napona. Kori&scaron;ćenje elekrospining tehnike ima brojne prednosti u odnosu na konvencionalne tehnike, pre svega zbog lakoće inkorporacije aktivne komponente u polimernu matricu, a i specifične morfologije i 3D strukture, jer usled nanometarskih dimenzija, vlakna imaju veliki odnos specifične povr&scaron;ine i zapremine i poroznosti, samim tim veliku kontaktnu povr&scaron;inu sa supstratima, reaktivnim agensima i mikroorganizmima. Zbog proizvodnje materijala na nanonivou, aktivna komponenta se fino dispergije u polimernoj matrici i time se obezbeđuje bolja aktivnost ovih materijala. Za razliku od konvencionalnih filmova, funkcionalni materijali na osnovu elektrospinovanih nanovlakana su aktivni po celoj zapremini. Cilj ove doktorske disertacije bio je optimizicija procesnih parametara elektrospininga i validacija aktivnosti funkcionalnih materijala za različite primene, &scaron;to je postignuto pravilnim odabirom materijala i aktivnih komponenti, optimizacijom sastava materijala, karakterizacijom materijala adekvatnim metodama i validacijom aktivnosti materijala. Razvijeni su materijali za primenu u oblasti kozmetike, ambalaže, filtracije, senzora, stomatologije i provodnih materijala, čija je aktivnost verifikovana u laboratorijskim uslovima (TRL 4).</p> / <p>Functional materials based on electrospun nanofibers are increasingly used in various fields of industry: biomedicine, pharmacy, sensors, filtration, packaging, etc. Electrospining technique is one of the methods for obtaining nanofibers from polymer solutions using high voltage. The use of electrospinning technique has many advantages over conventional techniques, primarily because of the ease of incorporation of the active component into the polymer matrix, as well as the specific morphology and 3D structure, because due to the nanometer dimensions, the fibers have a large ratio of specific surface area to volume and porosity, and thus a high contact surface with substrates, reactive agents, and microorganisms. Due to the production of materials at the nanoscale, the active component is finely dispersed within the polymer matrix, thereby ensuring better activity of these materials. Unlike conventional films, functional materials based on electrospinned nanofibers are active throughout the volume. The aim of this PhD thesis was to optimize the electrospining process parameters and validate the activity of functional materials for various applications, which was achieved by proper selection of materials and active components, optimization of material composition, characterization of materials by appropriate methods and validation of material activity. Materials have been developed for use in the fields of cosmetics, packaging, filtration, sensors, dentistry and conductive materials, the activity of which has been verified under laboratory conditions (TRL 4).</p>

Le marché de la cosmétique est l’un des marché les plus porteur actuellement dans le monde. La population française utilise énormément ces produits pour son hygiène quotidienne. Ce sont les shampoings ou autre crème de soins. Pour protéger ces produits, depuis maintenant de nombreuses années, les fabricants ajoutent des agents conservateurs pour augmenter la durée de conservation, ou encore éviter certaines contaminations microbiennes après les contacts avec la peau. Ces dernières années ont également vu les mentalités des consommateurs évoluer et actuellement, ces derniers souhaiteraient des produits cosmétiques le plus naturel possible, sans ajouts de conservateurs. Dans ce contexte, il semble intéressant de travailler sur la protection de ces produits par d’autres moyens. En premier lieu, nous vient immédiatement à l’esprit, la protection par l’emballage. L’idée est de modifier les emballages actuels pour leur conférer des activités antimicrobiennes et ainsi les rendre protecteurs. L’étude présentée s’intéresse à certaines possibilités de mises en oeuvre et modifications de polymères pour apporter une activité antimicrobienne. Deux voies de fabrications ont été étudiées dans cette thèse. Une première a consisté en la réalisation de revêtements antimicrobiens et protecteurs à basse température. Cette technique a montré la possibilité de créer des couches antimicrobiennes par photo-polymérisation à partir de monomères méthacrylates renfermant les agents antimicrobiens. C’est cette couche finale qui va venir s’ajouter à certaines zones spécifiques des emballages finaux pour assurer la protection antimicrobienne du contenu.La seconde voie d’action a étudié une fabrication plus industrielle à haute température. Cette technologie a permis de créer par extrusion des granulés antimicrobiens avec des introductions d’actifs de différentes natures. Ceux sont ces granulés qui sont par la suite injectés sous la forme d’emballages. Pour cette voie d’action, l’idée n’est plus de protéger l’emballage via une couche antimicrobienne, mais de substituer certaines pièces de l’emballage constituées de polymères naturellement antimicrobiens. Ces travaux ont permis la réalisation d’une large gamme de matériaux antimicrobiens. Les différentes solutions étudiées ont également permis de réaliser des prototypes d’emballages, ceci en collaboration avec certaines entreprises partenaires du projet. Tous ces prototypes seront prochainement testés en conditions réelles d’utilisations, c’est-à-dire par des essais de mises en contact avec le consommateur d’un système complet, à savoir le produit cosmétique conditionné dans des emballages protecteurs. Ces tests devront permettre de vérifier si les solutions proposées pourraient aboutir à une adaptation sur une chaine industrielle pour une utilisation à grande échelle / Today the cosmetic market is one of the most popular in the world. French people use many these products everyday as for examples, creams or shampoos. In order to protect the cosmetic products, the manufacturers introduced during these last year additives or conservative agents in cosmetic products to increase the shelf life or avoid a microbial contamination after a direct contact with the skin of consumers. However, recent years have also revealed that the consumer mindsets evolve and now, they would like cosmetics more natural, without addition of additives. In this context, it was interesting to work on the cosmetics protection by other ways. Firstly, we think immediately to the protection by use of packaging. The objective is to modify the current packaging to bring an antimicrobial activity and protect the cosmetics. This work presents different technologies of fabrication and modification of polymers to get an antimicrobial activity. For this, two techniques were studied. A first technology has consisted to develop antimicrobial coating at low temperature. This way has demonstrated possibilities of creation by photo-polymerization under UV radiations. Initially, the antimicrobial agents were introduced in liquid monomers before the polymerization and the fabrication of polymer networks. The final coatings were finally destiny to be added on specific areas of packaging, generally in contact with the consumers and prevent all risks of microbial contaminations from the products. The second technology has studied a way of polymer fabrication more industrial at high temperature. The technique has consisted to create antimicrobial pellets by extrusion with introductions of different natures of additives. The obtain pellets were injected at the end to fabricate certain pieces of the final packaging. This work has allowed the realization of a large range of antimicrobial materials. All the studied solutions have been used to fabricate prototype packaging in collaboration with partner companies of the project. All these prototypes will be tested by antimicrobial tests in real conditions of uses. If these tests prove successful, it will be possible to envisage an industrialization step
